Is there anything such as a particle failover with a palo alto firewall? Can it start to failover and suddenly fail back and block some traffic

There should be no partial failover.

Either active/passive or active/active.

Do you see failover event in System log?

I thought you were lauging at me LOL it seems to have lost it heartbeat connection but could that break anything once that condition is cleared?spiltbraind.PNG

If firewalls don't see each other over HA1 then both are active and accept sessions.

Shut down one firewall if you can't fix HA1 to get things up and running.

You have split brain situation.

Its no longer in split brain that I can see , but we could restart the passive firewall right now and see what happens. It is trying to send traffice to a router IP that no longer exists
